- クッション、
プレスのクッションに対して近接ないし離間可能に載置されたラム1、
前記クッションと前記ラムの間に位置する板押え3、
前記ラムに固定され、該ラムの下降に際して前記板押え3上に置かれた板材11を押し付けることが可能なダイ2からなるスタンピングプレスであって、前記板押えがさらに、
前記プレスの前記クッションに支持された前記板押え3を支持するための保持ピース4と、
前記板押えの周囲に設けられ、前記保持ピース4上に直接的または間接的に取り付けられた少なくとも1つの補償用流体シリンダー5であって、前記補償用流体シリンダーは前記下降するラムに対して直接的または間接的に接触し、およびダイ2が板材11に接触する前に前記下降するラムに対して直接的または間接的に力を加え、
前記少なくとも1つの補償用シリンダーに加圧流体を供給し、また圧力制御ポイントを有する少なくとも1つの調整弁とからなり、これによって、該補償用シリンダーによって加えられる力の全体Bが、前記プレスの前記クッションによって加えられる力Aを常に下回るかまたは等しい状態を維持しつつスタンピングプロセス中に変化し、前記ダイと前記板押えとのあいだの前記板材11に加えられ、かつ力AとBの差に等しい前記板押え力が、たとえ前記プレスの前記クッションによって加えられる力Aが一定であっても、スタンピングプロセス中に変化すること
を特徴とするスタンピングプレス。
